Frequently Asked Questions

Are these UUIDs really random?

Yes. They use the browser's cryptographic random number generator, the same source used for keys, so collisions are effectively impossible in practice.

Should I pick v4 or v7?

v4 is fully random and the safe default. v7 embeds a timestamp, so identifiers sort chronologically — which keeps database index inserts fast.

Are the generated values sent anywhere?

No. Generation happens in your browser, so nobody else ever sees the identifiers you create here.
